Two men in a bar crossover fic that works very well (even for someone ignorant of Farscape), with sharply observed characterisation and great dialogue, and a nice exploration of the gap between Nine leaving and returning for Rose at the end of Rose.

In a variation on the theme of The Lodger, the Doctor turns up on the doorstep of the main characters of Spaced, shortly followed by zombies from outer space. This is huge fun, whether or not you know the crossover, and Eleven’s character is spot on, and it’s all very entertaining.
